When Renili, Telenian Weaponist enters, you may exile another target creature until Renili leaves the battlefield.
When Renili leaves the battlefield, put a +1/+1 counter on each creature you control.

Whenever another creature you control is dealt damage, put a +1/+1 counter on it. If you do, upgrade Renowned Healer. (Give it one of the listed counters it doesn't already have. The damaged creature must survive to get the counter.)

If a player would conjure a card, they instead conjure a card named Data-Point. (It's a sorcery that costs {2} with “Draw a card.”.)
If a player would copy a spell or cast a copy, they copy the card named Data-Point instead of anything else.

This spell costs {2} less to cast as long as you've sacrificed an Idol this turn.

Creatures you control get +2/+1 until end of turn.

At the beginning of each end step, you may exile target creature card with mana value X or less from your graveyard, where X is the amount of life you gained this turn. If you do, create a token that's a copy of it.
